In the 1971 San Fernando earthquake the general performance of tilt-up structures was poor, and a number of collapses occurred. After this event substantial changes were made to seismic code provisions governing the design and construction of these buildings. The October 1, 1987 Whittier Narrows earthquake produced strong shaking (up to Modified Mercalli Intensity VIII) in an area containing thousands of tilt-up buildings of various ages. This recent earthquake thereby provided the first significant test of these new provisions.

Code Provisions

The Whittier Narrows earthquake has been the first earthquake to affect a significant number and many of the same elevator systems that now conform to the more stringent code provisions introduced after the 1971 San Fernando earthquake. While the relative damage potential of the two earthquakes is not now known, much less manchine room and rope damage was observed. The incidence of counterweights coming out of their guide rails was much less than it was from the San Fernando earthquake but still quite common. The performance and operation of elevator earthquake protection devices, seismic switches and counterweight derail detection devices, did not fully meet expectations but they did significantly reduce damage and the potential for injury. There was some inconsistency in the triggering of seismic switches. The seismic performance of elevators suggest that several changes to codes should be considered including a requirement to report earthquake damage and prevent seismic devices from being reset by unauthorized personnel.

Design And Construction

This article describes some of the safety considerations for the design and construction of micro/nano facilities and applicable building code provisions. The two key elements required for safe operation in micro and nanotechnology facilities are: (1) engineered features incorporated into building construction, and (2) administrative features that deal with how people work within the facility.
